With her superstar mom cryptically posting online from Ann Arbor on Wednesday, the profile of Lourdes Ciccone Leon now appears in the university's formal student directory, listing her as an undergraduate affiliated with the U-M School of Music, Theatre & Dance.

Freshman orientation for U-M's summer term began Monday and will run through Wednesday. Orientation for parents and family was scheduled for Monday and today.

Madonna posted an Instagram snapshot this afternoon of the fan-merchandise store the M Den - on State Street in Ann Arbor - with the caption, "I think ill stop in here!"

A store employee this evening said he could not confirm whether the 55-year-old pop star had visited the shop.

Typical freshmen start their college careers with the standard fall term, but special cases - including many student-athletes - begin during summer to settle in ahead of the fall commotion.

Madonna briefly attended U-M in the mid-1970s before heading to New York to pursue a dance career. She and Lourdes were spotted on the U-M campus in November as the teen was winding into her final year of high school.

Lourdes, 17, posted a column last week to the website for the fashion line Material Girl about the end of her time at New York's LaGuardia High School, writing "how very happy and slightly saddened I am that my high school years are now coming to an end."

Madonna's latest Michigan visit comes three weeks after her whirlwind visit to Detroit, where she dropped in on several community organizations.
